    Abstract : Given a grid of cells, each having a value indicating its cost per unit area, a variant of the least-cost path problem is to find a corridor of a specified width connecting two termini such that its cost-weighted area is minimized. A computationally efficient method exists for finding such corridors, but as is the case with conventional raster-based least-cost paths, their incremental orientations are limited to a fixed number of (typically eight orthogonal and diagonal) directions, and therefore, regardless of the grid resolution, they tend to deviate from those conceivable on the Euclidean plane.

  2. 2. Escaping 'death by GPS' : foundations for adaptive navigation assistance

    Author : Fateme Teimouri; Kai-Florian Richter; Henrik Björklund; Sabine Timpf; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wayfinding; navigation systems; navigation complexity; prominent locations; route generalization; spatial cognition; mental models; route learning; direction giving; Human-centered study.;

    Abstract : Navigating through physical environments has evolved over time from using stars and maps to support the wayfinding, to employing Global Positioning Systems and navigation services. Turn-by-turn guidance of navigation services is an effective way to support wayfinding, but it may not align with the way humans naturally navigate. READ MORE

  3. 3. Breakdown situations in dialogues between humans and socially intelligent agents

    Author : Maitreyee Tewari; Helena Lindgren; Kai-Florian Richter; Olov Engwall; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dialogues; Breakdown Situations; Focus Shift; Human-Centric Artificial Intelligence; Engeström’s Activity Triangle; We-Intention; Argumentation-Based Dialogues; Grice’s Cooperative Principle; Communicative Functions; Wizard-of-Oz; User Studies; Thematic Analysis; Sequence Organisation; Computer Science; datalogi;

    Abstract : Dialogues between humans are complex due to the challenges in predicting how they will unfold as people may want to achieve different purposes. For instance, to act together, they co-create a common goal; to learn, they co-create knowledge; to build relationships, they share emotions and beliefs. READ MORE
